MATLAB Image Segmentation Program Using Region Growing Method

In this article, we present a detailed guide on implementing an image segmentation program using MATLAB's region growing method. Region growing is a pixel-similarity-based segmentation algorithm that groups adjacent pixels into homogeneous regions by comparing intensity values or other attributes. We will thoroughly explain how to code an efficient region growing segmentation program in MATLAB, including key implementation aspects such as seed point selection, similarity threshold configuration, and neighborhood connectivity checking. Additionally, we will discuss enhancing the program with extended functionalities like image preprocessing techniques (noise reduction, contrast enhancement) and postprocessing operations (region merging, boundary smoothing). Through step-by-step demonstrations, this article will help you better understand the complete implementation process, with practical code examples showing how to handle different image types and optimize algorithm parameters for improved segmentation accuracy.
